[Optimization of the polymerase chain reaction (PCR) for detection and characterization of shigatoxin producing Escherichia coli (STEC) in food].
The polymerase chain reaction (PCR) was improved to detect shigatoxin producing Escherichia coli (STEC) in milk. Numbers of colony forming units (cfu) in test samples, concentrations and types of primers, amount of MgCl2, types of thermostable DNA-Polymerase, and cycling programs were modified up to obtain the cleanest electrophoretic pattern and the highest sensitivity. Experimental conditions for further characterization of STEC-isolates by means of PCR are given by summarizing data from literature.
